RELATIONSHIP BETWEEN INTERDIALYTIC WEIGHT GAIN AND PRE HEMODIALYSIS BLOOD PRESSURE IN HEMODIALYSIS PATIENTS

Interdialytic weight gain in patients with hemodialysis depends on fluid, salt intake in interdialytic period and compliance of dialysis patients. In end stage renal disease(ESRD) patients due to decreased and absent residual urine output there is salt and water retention in body which leads to interdialytic weight gain. Overhydration and IDWG is assumed to be the main cause of pre hemodialysis raised blood pressure(BP) in ESRD patients. Here the relationship between IDWG and pre HD blood pressure is studied in 40 hemodialysis patients. We recorded pre HD BP and IDWG in four subsequent hemodialysis sessions for each patient during the period of 2 weeks in patients who are on twice weekly hemodialysis. so, in total we studied 160 hemodialysis sessions. Mean of four pre HD BP is compared with mean of four IDWG for each patient. Then correlation between 40 mean IDWG and 40 mean pre HD BP is studied and also correlation between IDWG and pre HD blood pressure during 160 hemodidlysis sessions studied individually.
